Trusted HVAC Service in Fort Lupton

Fort Lupton is one of the older towns in southern Weld County, named for the trading post Lancaster Lupton built in 1838 and incorporated in 1890. For most of the 20th century it was a farm town of a couple thousand people. The population nearly doubled in the 1970s, from 2,489 to 4,251, and kept climbing to about 8,000 by 2020, with the housing count rising from about 2,100 units in 2000 to more than 2,700 in 2020.

That history leaves a wide range of HVAC equipment. Older homes near downtown often have furnaces that replaced earlier heating systems, sometimes venting through chimneys or flues that were never updated. Homes from the 1970s growth period are on their second or third furnace and AC, and the ductwork usually dates to the original build. Newer homes from the 2000s and later typically have high-efficiency condensing furnaces with PVC venting.

At about 4,915 feet, Fort Lupton sits a little lower than Denver, but furnaces still need correct gas pressure and combustion setup. We run a combustion and carbon monoxide test on every furnace call. For replacements, the City of Fort Lupton Building Department issues permits, with SAFEbuilt handling plan review and inspections, and contractors apply through the city's online portal.
